Oscilloscope watch

Doesn't appeal to me personally, but you have to admire the R&D involved in developing this sort of gizmo:

Bizarrely, its not that tough nowadays - most micro-processors have a decent amount of analogue processing capability, including fast mutl-channel ADCs (analogue to digital converters). Once in the digital domain, its all about software, which again, is not that complex.

Its likely, however, that this device is implemented as an FPGA (Field Programmable Gate Array) rather than a microprocessor and programmed in VHDL - again, the component count will be very low indeed. Natively, FPGAs can do very fast sample rates - up to 500Msamples/sec.

Probably more work in designing the mechanical components (case, screen, connectors etc).
